This is a pretty cool story.
[link to www.sciencedaily.com]
Basically they set a balloon up really high to collect multiple samples at multiple altitudes.
An excerpt:
In all, 12 bacterial and six fungal colonies were detected, nine of which, based on 16S RNA gene sequence, showed greater than 98% similarity with reported known species on Earth. Three bacterial colonies, namely, PVAS-1, B3 W22 and B8 W22 were, however, totally new species. All the three newly identified species had significantly higher UV resistance compared to their nearest phylogenetic neighbours. Of the above, PVAS-1, identified as a member of the genus Janibacter, has been named Janibacter hoylei. sp. nov. The second new species B3 W22 was named as Bacillus isronensis sp.nov. and the third new species B8 W22 as Bacillus aryabhata.
So, if 3 of the samples were completely different than the other samples which proved to be 98% similar to bacteria on earth, does that mean that they did not evolve on this planet???
maybe...
